Control System Design and Application of High Temperature and High Pressure Crushing Machinery

摘要:

为了实现高温承压破碎机械的连续运行，采用理论设计和模拟验证的方式，开发了一种新架构的电气控制系统。针对某石化项目工艺配置情况，将常规“一控一”防爆电气控制柜置于现场的形式，升级为“一控多”方式，并放置于安全区域，有效减小安全风险、减少成本、实现集中控制。控制系统采用西门子最新的PLC1517H冗余CPU，并通过冗余方式与分布式I/O进行通信。通过模块化编程、UDT结构、永久区域等方法，使编程、组态更加准确高效。采用安全可靠的MODBUS RTU与中控系统实现通信，使其可以监控设备的运行状态。通过现场运行反馈，控制系统保证了设备稳定、可靠的运行，操作、维护便利性较佳。

Abstract:

In order to realize the continuous operation of high-temperature pressure crushing machinery, an electrical control system with a new architecture was developed by means of theoretical design and simulation verification. According to the process configuration of a petrochemical project, the conventional "one control one" explosion-proof electrical control cabinet was upgraded to the "one control and multiple" mode in the form of the site, and placed in a safe area, which effectively reduced safety risks, reduced costs and achieved centralized control. The control system adopts the latest PLC1517H redundant CPU from Siemens and communicates with distributed I/O in a redundant manner. Through modular programming, UDT structure, permanent area and other methods, the programming and configuration are more accurate and efficient. The safe and reliable MODBUS RTU is used to communicate with the central control system, so that it can monitor the running state of the equipment. Through on-site operation feedback, the control system ensures the stable and reliable operation of the equipment, and the operation and maintenance convenience are better.
